Notes
The varieties cuspidata and brachyphylla are distinct from the type in appearance and may possibly prove to be distinct species, but there seem to be some intermediate forms, which require to be studied in the living state. The variety brachyphylla has the appearance of being a hybrid between E. striata and E. sclerophylla and only occurs in the general region where both species grow.
